Ark dev kit won't upload map to steam - says upload done but no maps are uploaded

As it says, gives no error - which given this uploader in no surprise - I’ve never gotten a fail error message as it just don’t have any - put in wrong steam id and password - no error given, that’s pretty **** poor, and wasted a huge amount of my time.
Cmd like window shows it logs in and such but it never uploads the maps - appx 1.8gb - gives link for steam workshop but I get this “Sorry! An error was encountered while processing your request That item does not exist. It may have been removed by the author” -

Surely given how ruff this uploader is it would have a detailed step by step guide - not the simple basic overview one I saw around - something with the finer details there are missing here - am I wrong? I’d love to be wrong were the full guide that will work?
